Specification of Letters Patent.

Patented sept. 1, 1914.

y.Application filed January 3, 1914. Serial No. 810,202. i

To all whom t may concern:

Be it known that I, CARL SCHEVITZ, a citizen of the United States, residing at Jacksonville, in the county of Duvaland State of Florida, have invented'znew and useful Improvements in Spring-Wheels, of which the following is a specification.

This invention relates to spring wheels,

the object ofthe invention being to` provide a simple construction of wheeliof the class described whereby` all ordinary road shocks and jars are absorbed between the hubv and rim onfelly ofthe wheel,"thefconstruction also insuring 'the thoroughbracingoflthe wheel as a whole both against transverse-and longitudinal strains. f ,f

With the above and other objectsy inview, the invention consists in the construction,

combination and arrangement of parts, asy

will vbe hereinafter more *fully described, illustrated and claimed.

' In the accompanying drawings z-Figure l is a side elevation partlyin section of a spring wheel embodying the present invention. Fig. 2 is a diametrcal section through one of the spokes showing also the hub.l and rim and the parts intimately associated therewith. n' f .n

Referring to the drawings 1 designates a continuousorendless rim, `2 vthewheel hub and A, generally, a series of spokes each of which comprises an inner member'or section 3 and an outer member or section 4. The inner section 3 may, if desired, be solid or tubular while the outer section 4 is tubular so as to form a socket'into which the inner section 3 is adapted to telescopeand slide. llhe inner section 8 is pivotally connected at 5to the hub while the outer section 4 is pivotally connected at 6 to the rimorfelly 1. Within the outer end portion of each sec- 5 tion 4 is arranged a coiled expansion spring 7 said spring being confined between the louter extremity lof the spoke section 3 and the rim 1.` In addition to the spring 7 another largery and longer coiled expansion spring 8 encircles both sections 3 and 4 of and the rim.

A. In order to adjust the tension of the spring 7, a chain'9 has one end attached to the outer extremity of each spoke section 3 and is provided `at its outer yend with ay threaded rodior bolt 41() upon which is threaded anutll. This nut has its outer edge notched as indicated at 12 to enable it each spoke, being confined between the'hub` i to be turned with the aid of a suitable spanf ner for wrench. Asv said nut bears against the outer extremity of the spring 7 it will be seen that by means ofsaid nut, the spring 7 may be initiallyv compressed or relaxed to any desired extentaccording tothe weight of thevehicle' and the load contained in the may be adapted to different loads while `retaining the necessary shock absorbing qualities referred to.

Any desired. formor construction of tire may be placed uponthe rim or fellyl, preferably a solider cushion tire of rubber or any other suitable material.

What I claim is j A spring,v wheel comprising an endlessrim, a hub arranged centrally thereof, a series of spokes each embodying telescopic `sectionsone of which has a jointed connection with the felly and the other of which has a jointed' connection with the hub, expansion springs arranged in the tubular spokesections and acting on the other spoke vehicle.I In this way the wheel as a whole sections slidable therein, stay chains conv nected at one end to the outer extremities of the inner spoke sections, threaded rods at the outer ends of said chains, and nuts threaded onsaid rods and adjustable in the tubular spoke sections and bearing against the outer extremities of said springs.

lIn testimony whereof-I afix my signature in presence of two witnesses.
